Valve sealing structure

Abstract

The invention discloses a valve sealing structure. The valve sealing structure comprises a valve body and a valve rod; a sealing structure is arranged between the valve body and the valve rod; the sealing structure comprises a groove formed on the valve body; the inside of the groove is of a wave-like structure; the wave-like structure is composed of raised triangular waves and raised trapezoidal waves, wherein the triangular waves are positioned at the two inner sides of the groove; the trapezoidal waves are arranged between the triangular waves and are distributed at intervals in the form of small trapezoidal waves and large trapezoidal waves; arc-shaped grooves are formed between the small trapezoidal waves and the large trapezoidal waves. The valve sealing structure disclosed by the invention is simple in structure, relatively low in cost, convenient to operate, relatively long in service life, capable of increasing the sealing degree between the bottom of the groove and a sealing ring by adopting the wave-like structure, and capable of realizing high-performance sealing because the small trapezoidal waves and the large trapezoidal waves in the wave-like structure can form a plurality of sealing structures.

AI Technical Summary

Benefits of technology

This technology improves on existing designs by creating multiple types of seals that improve their effectiveness with different levels of pressure or temperature conditions over time. It also simplifies its construction process while reducing costs compared to traditional methods like rubber rings.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the performance of valves that use liquified gases (liquid) during transportation. These valves have several key features: they allow different materials like water, chemicals, etc., to pass through without leaking out; they work with very small amounts of these substances at extreme temperatures while still maintaining their quality when kept cold enough outside. Additionally, there may also occur issues where certain solvents might break down overtime causing damage due to evaporation.
